Improve caching (#1014)

* Cache get place code for users and teams. 
    * Fix score changing test helpers to clear standings cache when generating a score changing row
    * `utils._get_config` will now return `KeyError` instead of None. 
    * Separate `/api/v1/[users,teams]/[me,id]/[solves,fails,awards]` into seperate API endpoints
* Install `Flask-DebugToolbar` in development
